Embodiment Construction
[0019] Such as figure 1 Shown, spectral analysis of the present invention is used for the physical examination method of plant seedling, utilizes Raman spectral image detection platform, detects the chlorophyll content of plant seedling under the stress of different base solutions:
[0020] a. Select a number of normal healthy plant seeds, put them into a container filled with an organic solution at room temperature for breeding, and analyze them with Raman spectroscopy after 10 to 20 days of cultivation;
[0021] b. According to the Raman spectrometer to obtain the detection spectrum of plant seedlings cultivated under the base solution, analyze the principal components of the full-band data, and select the principal components with a cumulative contribution rate of more than 95% as the input neurons of the neural network;
[0022] c. Modeling is carried out by using a neural network method to obtain the contents of chlorophyll a, chlorophyll b and total chlorophyll of the pl...
